It's an implementation detail, but an exposed detail, so, people refer
to the filename to find the timeline ID (That's why it happened to me)

Thanks, i got your point.

 Note that my proposal was to remove the ambiguous notation which
happen in some case (as in 11 <-> 17). A hint is useless in most of the
case, because there is no ambiguous. That's why i though format
hexadecimal everywhere.

At least, can I propose to improve the documentation to expose the fact
that the timeline ID is exposed in hexadecimal in filenames but must be
used in decimal in recovery_target_timeline and pg_waldump ?
